You are given the following information about x and y. x independent variable y dependent variable 4 12 6 3 2 7 4 6 refer to exhibit 14-6. the least squares estimate of b1 equals

Give me the equations of two lines that have the same slope but are not parallel.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Solve 13 + w/7= -18 (w/7 is a fraction)
